Abstract: 1,212,169. Card shuffler. K. MIURA. 6 Feb., 1969 [29 Feb., 1968], No. 6577/69. Heading A6H. In a card shuffler as shown, the feeder 27 is pivoted on the axle 32 and is provided with a divider blade 35 so that a pack of cards inserted into the feeder 27 in the vertical position shown in fig. 2 is divided into equal portions. The weight of the cards so inserted causes the feeder 27 to rotate into the delivery position and the above portions slide into the chute defined by the members 10 and 14. Said chutes are provided with gate plates 23 and 24 which only allow the passage of a single card, the cards being ejected from the shoots onto the pile (75c) (Fig. 7 not shown) by the rotation of the rollers 21 and 22. The rollers 21 and 22 are driven by the electric motor 46 via the cam pulley 50 and belt 54 arranged as shown in Fig. 3 so that the rotation of roller 21 is slightly in advance of the rotation of roller 22. In this manner cards from the lower shoot are made to fall underneath cards from the upper shoots onto the pile (75c). Power for the motor 46 is provided by the batteries 65 via the switch mechanism consisting of members 61, 61a, 61b, 62 and 63 which operate by the rotation of feeder 27. A window 75 is provided so that the shuffling process can be viewed. A second embodiment of the invention is given (fig. 7 not shown) in which the feeder is fixed in the delivery position and the above switch mechanism is dispensed with. In both of these embodiments, the width of the mouth of the feeder is adjustable in order to ensure that the divider blade splits an inserted pack into two exactly equal portions.

Abstract: 1455786 Quadraphonic decoders SANSUI ELECTRIC CO Ltd 14 Feb 1974 [21 Feb 1973] 6679/74 Heading H4R The gain coefficients of separation-enhancing, variable gain amplifiers in a 4-CH matrix decoder are variable about zero in positive and negative directions (the sign indicates phase). The decoder is otherwise as in patent Specification 1,402,320, in which composite input signals L, R Fig. 5 are mixed at 14, 17 to produce sum and difference signals which are amplified in the variable coefficient amplifiers 15, 21, 23, 18 and matrixed 51-54 to extract the four channels. Coefficient control signals Ef, El, Er, Eb are derived by phase comparison of L, R and L+R, L-R (Fig. 1, not shown) and subsequent compression to reduce the amplitude range. Each amplifier such as 15 has a signal input t 1  and bias terminal t 2 , a control input t 4  and reference t 5 , and an output t 3 . The difference is level between the control t 4  and reference t 5  is seized by a differential transistor circuit (60 Fig. 6, not shown) to turn on a logarithmic diode (D 1  or D 2 ) according to which level is greater. This turns on one or the other of two further differential transistor circuits (62) or (63) having logarithmic base-emitter characteristics effectively to multiply together the input at t 1  with the gain coefficient to produce a net output at t 3  whose amplitude and phase are proportional to the magnitude and sign of the difference between the levels at control and reference terminals t 4 , t 5 .

Title: Improvements in means for controlling the voltage applied to alternating current load circuits
IPC: G05F1/34
Filed: 1941-05-24
Abstract: 550,918. Control systems for resistance heating &c. BRITISH THOMSON-HOUSTON CO., Ltd. May 24, 1941, No. 6682. Convention date, May 25, 1940. [Class 38 (iv)] Voltage accommodation; inductive control.- In order to predetermine the voltage to be applied to a load circuit a reactor 17 is saturated to such a degree as will absorb the unrequired volts from a supply circuit 20, 21. To enable this to be done before the circuit is completed through the load transformer 16 by closure of the contactor 19 a second reactor 47 is connected as shown 15 saturated inversely in proportion to the saturation of the reactor 17. To determine the voltage to be applied to the load circuit and shown on the voltmeter 46 a condenser 26 is charged through a rectifier 30 to a voltage adjusted on a potentiometer 33 fed through a constant voltage transformer 34 from the supply 21. A condenser 27 is charged by impulses through a rectifier 30 in proportion to the voltage across tappings 40, 41 on resistances connected in series across the supply and respectively across the load circuit and the reactor 17. The voltage of condenser 27 is opposed to the positive voltage applied by the condenser 26 to the grid of a discontinuous control valve 22 which determines the saturating current of the reactor 17 as in Soecification 407,073. A valve 35 in parallel with the saturating winding maintains current during inverse half waves. The invention is described as applied to the low potential heating of a wire 10 or heating resistances.

Abstract: 198,766. Hamilton, W. March 7, 1922. Spindles.-The automatic adjusting device for compensating for wear or expansion &c. in poppet valve stems or other reciprocating or intermittent thrust mechanism described in Specification. 170,509 is simplified by the omission of the upper member therein provided with limiting abutments. The modified arrangement comprises only the following essential parts, namely, two nut members 4, 5 screwed upon a third member 1 with a spring 12 interposed so that when the parts 4, 5 are rotated in unison together they approach and recede relatively. The parts 4, 5 are mounted on screw threads 2, 3 of opposite hand and the spring tends to thrust the elements 4, 5 axially apart, and also prevents any substantial relative rotation thereof by engaging both of them positively, as shown at 13. A floating thrust block 8 or the like may be interposed, as shown, between the parts 5 and 9, e.g. the tappet head and valve stem, to prevent any turning effect of the part 9 on the part 5. The screw threads on the several parts may be interrupted, portions only of threads being used in the form of inclined surfaces having the same effect as a screw thread.

Title: Apparatus responsive to variation of the amount of wattless current
IPC: H02J3/18
Filed: 1944-04-12
Abstract: 606,650. Automatic control systems. COMMUNICATIONS PATENTS, Ltd., and ADORJAN, P. April 12, 1944, No. 6760. [Class 38 (iv)] Power factor.-In an automatic control system, control means respond to change in the relationship of the following currents associated with an electrical load presenting resistance and two parallel reactances of opposite sign: (a) the total load current; (b) the total load current less one of the wattless components. In Fig. 1, a fixed condenser 5 is connected in parallel with a predominating inductive load 4 supplied from an A.C. source 3. Solenoids 7 and 8, connected so that the latter carries the load current and the former the total current, exert opposing pulls on a rod 11, having ends of magnetic material, which is normally held in the position shown by a spring-loaded detent 14 engaging notch 12. Increase in the amplitude of the load current or its angle of lag results in a change in the relative value of the currents in solenoids 7 and 8 which, at a predetermined value of the increase, causes rod 11  to move to the position at which detent 14 engages a notch 13 and contacts 15 are closed to energize a relay 19 connecting a condenser 18 in parallel with the load for power factor correction. The following modifications of this arrangement are referred to: (a) Adjustment of the operating point by varying the spring loading of detent 14. (b) Substitution of magnetic restraining means in place of the spring-loaded detent. (c) Connection of condenser 5 only when the load exceeds a predetermined minimum value. (d) Use of electrothermal means in place of solenoids 7 and 8. (e) A reversible electric motor, controlled by the two currents, operating switch means to introduce one or more compensating condensers. In Fig. 2 the solenoids 7 and 8 of Fig. 1 are replaced by current transformers 22, 23 which produce, through metal rectifier bridges 25, 26, D.C. voltages across resistances 31, 32 proportional to the currents in their primary windings. A relay 34 differentially energized by these voltages closes its contacts 36 under conditions similar to those which cause contacts 15 to close in Fig. 1 and a relay 39 is energized from a transformer 38 to connect condenser 40. A similar circuit involving transformers 23, 24, resistances 32, 32, relay 35 and relay 41 controls the connection of a second condenser 42 to compensate for a further increase in inductive load. The arrangement may be extended to introduce more than two condensers. The operating points of relays 34, 35 are adjustable by varying resistances 31, 32, 33. Positive operation of relays 34, 35 is ensured by mechanical or magnetic restraining means (not shown). If the load is likely to become non- inductive these relays are polarized.

Title: Improved apparatus for use in games
IPC: A63F9/14
Filed: 1924-02-14
Abstract: 215,890. Roberts, H. M. Feb. 14, 1924. No Patent granted (Sealing fee not paid). Race games, mechanical.-Relates to apparatus of the type in which a series of figures are raced up an inclined track towards a second series of figures, the leading figure causing the corresponding figure of the second series to change its position, and consists in that each figure is connected to a winding drum provided with a sprocket wheel adapted to be rotated by its engagement with one end of a hand-operated lever, but free to rotate in the reverse direction if the oscillation of the lever be discontinued. As shown, one of a series of racing figures b, mounted on wheels b<4> adapted to run between guides a<a>, a<3> arranged beneath slots a<1> in an inclined platform a, is connected by a cord c<4> passing round guide pulleys c, c<1>, c<2> to a. winding drum c<3>. A sprocket wheel d<4> attached to the drum c<3> is adapted to be engaged by the pivoted end d<5> of a hand-operated lever d, by the oscillation of which the drum is caused to rotate and the figure b to climb the track. If the handle d is left free or held in an inclined position the drum rotates in the reverse direction and the figure, moves down the track under the influence of gravity. A second series of figures f arranged at the top of the tracks are pivoted on pins f<2>, and are weighted at one end h, being held in their normal positions, Fig. 2, by cords f<4> attached at one end to pegs f<3> on the figures and at the other to pivoted platforms g. When the leading figure b reaches the top of its track it depresses one of the pivoted platforms against the action of a spring g', and allows the corresponding figure f to swing through 180‹ to the position shown in Fig. 3. As the figure turns it actuates a switch m<1>, causing a bell n to ring and closing a circuit through a lamp m, thus indicating the winner. The figures may also be arranged to operate a rod k, Fig. 7, situated beneath the front board p and adapted to lock the levers d in a position which allows the figures b to return to their starting positions. On the return of the figures b, the depressed platform g is released and the inverted figure f resumes its normal position.

Abstract: 927,505. Automatic speed and tension control. FERNSEH G.m.b.H. Feb. 24, 1961 [Feb. 27, 1960], No. 6861/61. Class 38 (4). [Also in Group XX] When a film 3 is initially drawn through gate 1 by sprocket 2, sprocket 5 is not rotated, so that the output shaft 19 of differential 9 moves slider 13 to increase the effective resistance of controller 14. This increases the torque exerted by motor 10 on spool 4, the speed of the film moving over sprocket 5 increasing from zero whereby the speed of the shaft 19 is reduced. This in turn reduces the torque transmitted by coupling 11, and thus the slider 13 is returned towards centre tap 24 until the speeds of the film moving into and out of the loop formed by roll 6 are equal. During the period in which these speeds are unequal, a lever 7 is moved to turn the resistance element of controller 14 so increasing the torque exerted by motor 10 until the reduced size of the loop returns the resistance element to its initial position. Since the control signal so obtained is proportional to the loop-length it is also proportional to the time-integral of of the difference between the entry and exit speeds. In another arrangement, the differential 19 is dispensed with, and the speeddifference is detected by measuring the angular velocity of the lever 7. This lever is geared to shaft 19 controlling the movement of slider 13 in accordance with the torque transmitted by fluid coupling 11 and acting against spring 12, Fig. 2 (not shown).
